To oLZZ whom, it may con/cern): Y i

Be it known that I, PAUL BRANDSTEDT, re siding at Washington, in the District of (3o` lumbia, have invented a new and Improved Metal Studding or Partition, of which thefollowing is a description. y

This invention relates generally to a fireproof building construction, and more specifically to an improved metallic member adapt ed to serve as a stud o r ceiling-support, having means for conveniently attaching metal laths thereto; and primarily this invention seeks to provide a stud or supporting mem-v ber for the, purposes stated of a very simple and inexpensive construction, capable of being conveniently handled and set up for use, and to effectively serve for its intended purposes.

In its generic nature my invention comprehends a corrugated sheet-metal member having two opposite edges equipped .with lathclamping members to receive the lathing from either or both sides and a securing member at the lower end for making Vfast to theoor joist or beam, upon which it rests,land means at the upper end whereby it can be conveniently made fast to the ceiling-joist or I-beam without the use of nails or other separate fastening means. v

My invention in its more specific nature also embodies, in a metal stud having means for making fast at the lower end, an upper extensible section having speciallyfformed portions for connecting with the ceiling-joists or I-beams and having its'lower portion provided withv slots adapted .to receive clamp ends of metallic bridging-sections forming'a cooperative part of my improved construc-v tion of studdiug, or when used aspartition member and to receive hangers for sustaining the same from overhead I-beanis or joists when usedas a ceiling-support.

Again, my invention has for its purpose to provide an improved form of metallic'stud or ceiling member adapted for use against a solid wall as a partition member or as a supporting means for the hanger-rail of sliding Idoors or partitions.

ticularly pointed out in the appended claims, reference being lhad to the accompanying drawings, inwliichf Figure lis a View illustrating my invent-ion adjusted for-use as a studor partition structure. Fig. 2 isa horizontal section of the same as lapplied for use against a solid wall to receive lathing on one side only and embedded in a solid` layer of plaster. Fig. 3 is a similar section showing the same used as a partition-stud to receive the plasterl on both sides. Fig. 4 is a perspective view of one of themetallic sections with the vextensible scction. Fig. 5 is a view ot' the extensible section detached. f Fig. 6 is a cross-section substantially on the line 6 6 of Fig. 4. Fig. 7 is a View illustrating my invention arranged to act as a ceiling-support. Fig. 8 is a side elevation of one side of a portion ofthe stud or supporting member. Fig. 9 is a vertical section thereof, taken substantially on the line 9 9 ot Fig.' 8 and showing the manner of clamping a lath thereon. i Fig. 10 isa view Fig. ll is a detail horizontal section on the line 11 l1 of Fig. l. Fig. 1li is a detail section on the line a a of Fig. ll. illustrating the manner of arranging my irnproved stud for supporting the hanger or rail for slidingA doors or partitions.

Referring now to theaccompanying'drawvings, in whichA similar letters indicate like parts in all the gures, l designates my im- Figs. 12 and 1.2a are views Y 'proved metal member, vwhich is formed of sheet-iron and which to provide for strength, rigidity, and great tensile strain is corrugated or pressed up into the shape shown in the several horizontal sectional views thereof, by reterence to which it will be noticed the same consists of a metal plate bent centrally in the direction of its length into a U shape, the sides 2 2 of the body being bent back in parallel vertical planes to produce two opposite dat surfaces 3 3, adapted to receive the lathing, which by reason of the iiat surfaces 3 3 can be placed against either or both of the sides 2y 2 and to provide for conveniently, quickly, andy effectively securing. the laths 4 4: to the stud or supporting. member l, the faces 3 3 havinggdiagonal slots 3 3, which extend through the free ends of the sides 3 3, whereby to produce bendable clip mein y bers 3b 3b, adapted to be bent over the laths, as clearly shown in'Fig. 9, andv thereby firmly clamp them upon the sides of the studs without the use of nails or other additional fastening means. It is manifest that by bending that part of the body portion between the parallel sides 2 2 inward, as shown and described, the member 1 is rendered one of great strength and rigidity, and the sides thereof will have sufficient resiliency to permit of a limited expansion or contraction thereof Without affecting the complete construction ofthe partition. l

In the simplest form-that is, when thestud or member 1 is specially made and of a desired length-the lower end of the U-shaped body portion is extended in a flattened condition and bent inward at right angles to produce a footpiece 6 for resting upon the oor, 1

to which said piece 6 maybe secured by spikes or screws; but when the stud is to be used in connection with I-beams above and below the sides 2 2 are extended at both ends, as at 'a 7, which form side clamps adapted to bend over the flanges of the I-beams, as clearly shown in Fig. IO.

In the manufacture of metallic studs or partition-supports it is usual to make them a standard length. In my construction of stud the same maybe also of the standard length; but to provide for its use for partitions of greater length I provide a supplemental telescopic section adapted to be detachablyjoined with the upper end of the member 1. This supplemental section (designated by 10) has substantially the same cross-sectional form of the member l; but to provide for a rigid joint betweenthe two members, so as not to weaken the complete stud, the angle sides 10a of the central or U-shaped part of the member l0 are slitted longitudinally, as at 10b, to produce turned flanges 10, adapted to ride over the edges 1C of the member 1, as clearly shown in Fig. 6. By thus joining the two members the part 10 can be readily slid up or down to lengthen or shorten the stud to a height desired, and by reason of the member l0 eX- tending under the same part of member 1v and the flange l0c fitting over the edges lc; of the member 1 the parts are joined firmly to form a continuous member, and buckling of the same at the joint is entirely overcome. The sides of the member 10 are also slitted, as at 10d, to provide the lath-securing clips, as shown, and the said sides are also extended to forni strap members 10E l0e for clamping upon and bending over the I-beam flanges or for making fast to ceiling-beams when of wood.

My metallic stud is intended to serve as a substitute for the usual Wooden partitionstud, and in the practical use the said studs may be set sixteen inches (more or less) apart, as usual.

To provide for strengthening the studs, especially against buckling in alengthwise direction, I provide the base of the U-shaped body with horizontal slots 1f, adapted to receiveA tongues or projecting lips 15a of supplemental metal members 15.v This latter member l5 in the simplest application of my invention, especially where the studs are closely set, need not be used; but when the studding is widely separated said braces 15 will serve to-take up the longitudinal strain and maintain the studs in their proper lposition.

In Figs. 12 and 12a I have shown 110W my improved metallic studs are arranged for sustaining the guide-rail of sliding doors or partitions. For this purpose the cross-brace, in the nature of a plate 16, to which the hanger 17 is secured and made toproject sufficiently below the plate to allow for a proper clearance of the roller or slidel member (not shown) onv the door, and to firmly secure the plate 16 it has two or more bendable-clip ends 16 at each end to engage the slots in the opposite studs 1, as shown.

While I have described my improved stud as more especially adapted for fireproof buildings, it is obvious the same may be used as a partition for ordinary buildings and madeV to support wooden laths.

From the foregoing description, taken in connection with the accompanying drawings, it is thought the manner in which my form of metallic stud or supporting member is capable of being used and its advantages will be readily apparent to those skilled in the art to which it appertains.

` The construction is such that the same can be economically and conveniently employed for supporting metallic laths for side walls and ceilings and readily made fast in a vertical position and suspended horizontally.

While I prefer to bend the inner or body part of the metal plate'in the manner shown and described, said body portion may be corrugated or fluted, and the several minor details of construction may be also slightly modified or varied without departing from the scope of the appended claims.

By constructing the stud members in the manner described it is manifest that when assembled to form partitions air-spaces are pro- Vided,which renders the partitions practically sound-proof. This latter feature, so far as I know, has heretofore not been provided in the ordinary types of metallic stndding.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. A sheet-metal stud, comprising a central corrugated body portion, the free ends of which are bent back in parallel planes to form lath-receiving surfaces, said surfaces having bendable portionsto clamp the laths, for the purposes specified.

2. A metallic studpartition,comprising vertical U -shaped studs,each having supplemental parallel side members, having lath-clam ping members, said U -shaped body having slots, and a brace-stud provided with project- IOO TIO

ing member, comprising a body portion U-A shaped in cross-section, and having its sides bent to form resilient latki-attaching portions,

'said portions havingbendable members adapted to clamp over the laths, for the purposes specified.

4. As a new article, a metal sind or supporting member, comprising a body portion U-y sbaped in cross-section, its free sides havingI extensions bent to form opposing parallel sides, said sides having diagonal notches, whereby to provide bendable clamp members, for the purposes specified.

5. A metallic stud consisting of a body, U- shaped in cross-section, the sides of whichv have extensions bent to form vparallel faces, said sides having bendabie clamp members, and a supplemental member slidably mounted thereon ,having parallel sides providedwith lath-ciamp portions, said sides having bendable extensions, for the purposes specied..

G. As a new article, a metal stud or supporting member, comprising a main'body U-l shaped in cross-section, the sides of which are extended and bent to form opposite parallel lath-receiving sides, and a detachable supplemen tal portion, consisting of a U-shaped'portion, the opposite sides of which are sli'tted longitudinaily, said sides having vextensions bent to 'form opposing lath-receiving sides, the latch-receiving sides of the two parts having lath-clamping members, for the purposes specified. l 7. In a metallic studdingor partition of the charaoterdescribed,the combination with twoy studs, each formed of sheet metal and consist-ing of a U-sbaped body portion, thesides of which are bent to form opposing parallel vsides to form lath-holding surfaces, the cross PAUL BRANDSTEDT.
